During the last meeting, we were discussing Zeek (formerly Bro) and narrowing down choices for sniffing accessories (tap vs span port). We settled on the Great Scott Gadgets lan taps. The pro version is enclosed and complete for $40, and the Throwing Star version is in kit form and just $15. Because I’m (a) cheap, (b) addicted to flux fumes, and (c) a ninja, I opted for the throwing star. I just slapped it together in about ten minutes, and it seems to be working just fine.
Of course, since I got it from Hacker Warehouse, it also came with stickers.
